World Happiness Report

The World Happiness Report has proven to be an indispensable tool for policymakers
looking to better understand what makes people happy…

Ingest

df <- read_xls('./archetypes/happiness-report/happiness-report-2020.xls')
df

Dimensions

number of columns and rows

dim(df)

## [1] 1704   26

The output tells us that the data contains 1704 rows, and 26 columns.

Positive, Negative and Zero Values

Check for all the numerical columns

df1 <- df[,3:ncol(df)]

nRows <- dim(df1)[1]

calcStats <- function(x) {
  temp <- na.omit(df[, x])
  pos <- sum(temp > 0)
  is_zero <- sum(temp = 0)
  neg <-  sum(temp < 0)
  c("number of positives" = pos, "negatives" = neg, "zero" = is_zero)
}
  
result <- as.data.frame(Map(calcStats, colnames(df1)))
result

Histograms

for all numerical variables

df_long <- df %>%
  pivot_longer(
    `Life Ladder`:`Most people can be trusted, WVS round 2010-2014`,
    names_to = "measure",
    values_to = "value"
  )

v1 <- ggplot(df_long, aes(x=value)) +
  geom_histogram(fill = "#79B8E5") +
  facet_wrap(~ measure, scales="free")+
  theme(panel.grid = element_blank(), 
        strip.background = element_blank(),
        panel.background = element_blank()
 ) 

girafe(ggobj = v1, width_svg = 16, height_svg = 9, options =
  list(opts_sizing(rescale = TRUE, width = 1.0))
)

Just looking at the graph, we see that the “Life Ladder” varies from 0 to 8, with the majority of values between 4 and 6. “Log GDP per capita” varies from about 5 to 12. So the GDP per person would vary in this dataset from $150 to $160k.
